ENVIRONMENTAL AND EMC TEST LABORATORIES

Shock and Drop Test Facilities

A wide range of shock tests, drop tests, and data analysis.

The shock test facilities have been developed to reproduce the mechanical shock environments that occur when pyrotechnic devices are fired during spacecraft launch and deployment operations.

There are two main facilities available and are selected depending on the test levels required and unit size. The facilities have a flexible design and can be tailored to suit individual customer requirements based on the nature of the testing, variety of units and shock levels required. The facilities are continually being expanded and upgraded to suit all types of test units.

The shock rigs main components are a hammer and resonant plate. The shocks are produced via a free falling mass (hammer) striking an anvil attached to the ringing or resonant plate. The test article is attached, usually directly, to the ringing plate.

Half-sine shocks can also be produced using a free-fall drop rig.

Classical shock profiles are generated using conventional electro-dynamic vibration systems.
